Roan sien on SIGNAL.

f Application led October 24, 1923. Serial No. 670,611.

My invention relates to improvements in road signs or signals and moreparticularly to that class of signals consisting of light reflectorsyadapted for arrangement at road tersections, crossings or dangerouscurves, warn approaching motorists of danger.'

The object of my invention is to construct a signal or reflector ofmirrored glass, prefthe light raysl from such a manner curve or crossingas the case may be.

Another object is or reflector that may and reflector nears saidreiector.

Other objects and companying sheet of drawings, iii which:

f Fig. 1 is a diagrammatic view illustrating pair of reflectors at abend or curve-in the roadwayin accordance of my invention; saidreflectors being placed slightly within the apex formed by the outerlines of said roadway and the method of placing a with the principleseach facing one arm of the roadway.

Fig. 2 is an elevation of an to produce Such a sign be of any design orsize l placed in such relation to curves or turns of the highway that itwill be discernable at least a half mile away, that is in case of asubstantially straight highway leading up to said and the reflected raysbecoming stronger and more brilliant as the machine.

advantages and the features of construction of the invention willVappear in the subjoined description ofthe acembodiment of my inventionshown in the form of an'arrow.

Fig. ment showing a curve sign arrow. Fig. of supporting the upon line4-4 of Fig. 2.

Fig. 5 is an enlarged transverse section showing the flutationsA orcorrugations of the reflector, taken upon line 5-5 of Fig. 4.

As disclosed in the accompanying drawings the signs'or reflectors maybemounted in any support or at the corners of distance from the ground toproperly receive and reflect the rays of light and distribute themsomewhat lat suitable frame or buildings anda suitable 5c 3 is anelevation of another .embodiinstead of the 4 is a verticalsectionshowing a method reflector sections, taken tallic material.

erally and not above or below the rangel of vision.

The reflector is preferably constructed of iiuted glass, with theflutations extending vertically when the reflector is in position uponthe support. Said flutations receive rays of light and project them in asubstantially fanshaped beam with relation to the flutat-ions of thereflector and laterally of said llutations.

The mirror or reflector may be any shape o r design and preferablyconstructed in sections, so that any one section may be remo-ved andreplaced if. broken and may consist of an ornamental glass. Theflutations or corrugationsiu the glass extending vertically thereof toproduce a slight prismatic effect upon the incident rays to widen outthe reflected beam ;v so that it may be visible from any part of theroad within the line of approach.

Referring to Figs. 2, 4 and 5. (l) in a general way designates thereflector preferably consisting of several sect-ions of mirrored glass(2), cut to imitate any desired configuration, such as, an arrow; saidsections (2) are held in place by a frame (3) of light me- Said frameconsists of a back support (4) having outwardly extending portions (5)and retaining langes (6). This frame (3) may be nailed or otherwisesecured to a board (7) which in turn is bolted to the upright or post(8) by bolts (9).

The sections (2) are silvered on their in- `outer or both faces andextend vertically from' the lower to the top edgesof said sections.These iiutations are molded or rolled in the glass and when consideredtransversely the contour thereof forms a continuousfseries ofconcave-convex surfaces'.

I have shown and described the reflector (l) as of mirrored glass, butit is to be understood that said reflect-or may be constructed of ahighly polished metal such as aluminum or brass having the liutationsextending vertically thereof in the same manner.

The metal construction would necessarily be provided with a coloredglass front to produce desired colored or cardinal diffusions.

Having thus illustrated and described my invention inf= its preferredform, I Wish it understood that the same may be modified as practicesuggests. Therefore, the patent protection that I desire is all of thatwhich comes 5 Within the spirit and scope of the invention as claimed. Iclaim: In a signal of the class described, a plate of transparentmaterial having a lane reiiecting back surface and a iuted ont surface,the signal being adapted to disperse therefrom a beamof light fan-shapedin a substantially horizontal plane when the plate is positionedvertically with the flutes thereof vertical and at a desired point inthe road.
